If you haven't been playing multiplayer Modern Warfare 2for the past week or so because it's an exploit-ridden mess, you can go back to war now: Infinity Ward has issued a patch for the PC, 360 and PS3 that clears up many of the game's worst issues, including:

1887s Balanced.

Public "private" Match fix.

Infinite Ammo fix.

Prestige Hack on PS3 fix.

Texture Hack on PC fix (eliminates any edits to IWD files also).

Sadly, the "I suck at this; stop shooting me" glitch is apparently still in effect, as people keep shooting me. Full patch notes will be released after the holidays.
